DRINKING WATER CASE STUDIES AND WHITE PAPERS

• Innovative Communication Tool Enables Robust And Contact-Free Control Capabilities

  Two-way wireless communication can provide a wealth of benefits for municipal water utilities, including command and control abilities that underpin a wider smart city infrastructure. However, most tools currently on the market do not provide the flexibility and uncompromising speed that are necessary to enable these capabilities. The newly released Mueller® Mi.Net® LoRaWAN® (LW) node, by comparison, allows two-way data communication to take place within seconds instead of hours.

• Upgrading From Gas Chlorine To On-Site Hypochlorite Generation To Improve Safety And System Resilience

  By replacing gas chlorine with on-site hypochlorite generation, Nashville was able to improve the safety and longevity of its water plants to accommodate the growth of the “Heart of Country Music” far into the future. At a recent water conference, Glen Doss, Treatment Plant Manager stated, “In 2016, the last gas chlorine railcar left to large applause.” 

• AMI Reluctance And The Risk Of Doing Nothing

  Water utility systems that have transitioned to AMI benefit from increased revenue, reduced risk, improved customer relations, and widespread efficiencies across operations.

• Hydra-Stop Solutions Isolate Damaged Valve During Water Main Replacement

  The Village of Covington, Ohio had an ambitious 90-day project to replace the water main, taps, sewer main, laterals, and storm sewer through the center of town. Unfortunately, on day one, an unknown water service line was snagged and the top half of an 8” valve blew off, causing water to shoot 10”–12” out of the street.

• Electromagnetic Meters And Ultrasonic Meters — A Comparison

  Water and wastewater professionals rely on accurate flow measurements for process operation and regulatory compliance. Selecting the best flow meter for each application is essential to obtaining accurate flow data.

• Village Blue Lake Pontchartrain Offers New Orleanians Insights Into Local Water Quality

  Water quality monitoring can be a powerful tool to help inform policies and environmental restoration efforts, and to keep local water bodies healthy. EPA recently launched a water quality monitoring project in New Orleans that’s helping the community learn more about Lake Pontchartrain’s water quality and its greater connection to the Mississippi River.

• EPA Scientists Test Non-Targeted Analysis Methods Using Drinking Water Filters

  Today, researchers can rapidly search for thousands of never-before studied chemical compounds in a wide variety of environmental, residential, and biological media. This approach is called “non-targeted analysis” (NTA). It differs from targeted analysis because researchers do not have to know what specific chemical they are looking for in a sample. They can use high-resolution mass spectrometry (HRMS) to rapidly identify many of the chemicals present in a sample. The HRMS measures the accurate mass of molecules and can find chemicals that would have gone unnoticed before. This approach is beneficial not just to researchers, but to States, tribes, and local communities who might want to know more about chemical exposure.

• Fuel And Fuel Additives

  The fuels that propel modern society have been found in water supplies all over the world. Some fuel-related contaminants can be found at a majority of the United States Environmental Protection Agency’s (USEPA) National Priority List Sites, where they pose a potential threat to human and environmental health.

• Lease vs. Purchase: A Guide To Maximum Cost Savings For Chlorine Dioxide Systems

  Chemical dosing for disinfection is a critical step in the drinking water treatment process, but the available solutions are often expensive. A high-quality chlorine dioxide system can address the need for disinfection as well as taste and odor control while minimizing disinfection byproducts, but the acquisition should be properly structured to be as economical as possible. Water Online spoke with JCS Industries President Brian Whitmore about the important factors to consider in determining which option for a chlorine dioxide system makes the most financial sense.

• Valve Health Diagnostics

  Valves are one of the most common assets in the process industry, spanning all verticals. Chemicals, refineries, and petrochemicals, however, will find improved valve health diagnostics useful for critical valves and controllers in their plants, while upstream and midstream oil and gas companies may be focused on much larger, critical valves like pipeline or subsea valves. Using Seeq, process manufacturers are able to implement a condition-based monitoring analysis to monitor valve health across an entire fleet. Engineers can utilize the historical data to accurately create a predictive maintenance forecast and preemptively detect valve failures before they occur.
